我正在为游戏制作一个计算器
我通常首先确保代码在C ++中工作,然后将其转换为所需的语言。我做了这个程序。在这个程序中,有些时候,optDura存储正确的值和其他时间,它存储垃圾。
这是代码: -
#include <iostream>
using namespace std;
/*
cd - current Durability
se - smith efficiency in decimal
sc - smith charges in decimal
sE - smith efficiency in %
sC - smith charges in %
ic - initial cost
md - maximum durability
tmd - temporary maximum durability
tD - temporary durability
td - total durability
rc - repair cost
cpb - cost per battle
*/
int main(){
long int currDura, maxDura, tempMaxDura, tempDura, totDura, optDura;
double iniCost, repCost;
long int smithEffi, smithCharge;
double se, sc;
double totCostTillNow, costPerBattle = 0, minCPB;
int i;
long int repCount = 1;
iniCost = 25500;
currDura = 58;
maxDura = 59;
repCost = 27414;
se = 0.90;
sc = 0.85;
tempMaxDura = maxDura;
tempDura = currDura;
totDura = tempDura;
totCostTillNow = iniCost;
costPerBattle = totCostTillNow / totDura;
minCPB = costPerBattle;
cout<<"\n Cost without any repair = "<<costPerBattle;
for(i=1; i<=maxDura; i++)
{
totCostTillNow += (double) repCost * sc;
tempDura = tempMaxDura * se;
totDura += tempDura;
costPerBattle = (double) (totCostTillNow / totDura);
tempMaxDura -= 1;
if ( minCPB >= costPerBattle )
{
minCPB = costPerBattle;
optDura = tempMaxDura;
}
}
cout<<"\n Minimum cost per battle = "<<minCPB<<" & sell at 0/"<<optDura;
return 0;
}
当repCost为&gt; = 27414时,会出现问题。对于小于该值的值,它会给出所需的结果。我无法弄清楚为什么会这样。
非常感谢

如果你重写初始化你的变量而不是使用&#34;声明并分配&#34;抗 - &#34;模式&#34; (我也删除了未使用的变量):
int main(){
long int currDura = 58;
long int maxDura = 59;
long int tempMaxDura = maxDura;
long int tempDura = currDura;
long int totDura = tempDura;
long int optDura;
double iniCost = 25500;
double repCost = 27414;
double se = 0.90;
double sc = 0.85;
double totCostTillNow = iniCost;
double costPerBattle = totCostTillNow / totDura;
double minCPB = costPerBattle;
cout<<"\n Cost without any repair = "<<costPerBattle;
for(int i=1; i<=maxDura; i++)
{
totCostTillNow += repCost * sc;
tempDura = tempMaxDura * se;
totDura += tempDura;
costPerBattle = totCostTillNow / totDura;
tempMaxDura -= 1;
if ( minCPB >= costPerBattle )
{
minCPB = costPerBattle;
optDura = tempMaxDura;
}
}
cout<<"\n Minimum cost per battle = "<<minCPB<<" & sell at 0/"<<optDura;
return 0;
}
然后optDura
成为唯一缺少初始化的人
它唯一分配值的时间是minCPB >= costPerBattle
,因此,如果该条件永远不会让您留下不确定的值。
将其初始化为合情合理的东西。
